sphinx是一个高效的搜索引擎,分词搜索的速度比较快,索引建立存储在硬盘文件,不会干扰数据库,有自己内置的一套数据库.
php中使用sphinx搜索引擎
sphinx是一个高效的搜索引擎,分词搜索的速度比较快,索引建立存储在硬盘文件,不会干扰数据库,有自己内置的一套数据库
1.ubuntu安装sphinx
如果没有安装aptitude ,需要先安装 aptitude 因为因为用apt get install 安装下面命令会出现问题.sudo apt-get install aptitude
sudo aptitude install sphinx3 sphinx3-doc sphinxsearch sphinx-common -y
2.配置

}

- 执行命令分词,会在/var/lib/sphinxsearch/data/test1 目录下生成一堆索引文件
sudo indexer -c /etc/sphinxsearch/sphinx.conf test1
test1为上述配置文件的index名字
4.命令行测试搜索
sudo search -c /etc/sphinxsearch/sphinx.conf google
二.在php中使用
1.安装php sphinx的依赖库
1.安装 aptitude
apt-get install aptitude
sudo aptitude install libsphinxclient-dev libsphinxclient-0.0.1 -y
2.安装php sphinx的扩展
安装 peclsudo apt-get install php-pear php5-dev
在安装sphinxsudo pecl install sphinx
3.在配置文件php.ini中添加sphinx的扩展,
我的php.ini文件为sudo vim /etc/php5/fpm/php.ini
获取自己的php.ini文件位置使用php5-fpm -i|grep ini
添加:extension=sphinx.so
4.重启php5-fpm,查看php是否加载sphinx模块sudo /etc/init.d/php5-fpm restart
5.将search程序运行在后台sudo searchd -c /etc/sphinxsearch/sphinx.conf
默认监听配置文件中的端口:9312
6.在thinkphp中调用搜索

public function testSphinx()
{
$s = new \SphinxClient;
$s->setServer("localhost", 9312);
$s->SetArrayResult (true );
$s->setMatchMode(SPH_MATCH_ANY);
$s->setMaxQueryTime(3);
$result = $s->query("test");
$result = $result['matches'];
$result = array_column($result,'id');
$list = M('CouponApi')->field('couponid,title,description')->where(array('couponid'=>array('in',$result)))->select();
dump($list);
}
|
搜索完毕,返回结果(默认返回20条,修改返回条数用添加 $s->SetLimits(0, 1000, 1000);
),搜索速度相当快,索引80w条数据的title和description两个字段耗时不到10s,该搜索引擎支持增量索引,多种模式的搜索,网上的资料也非常多
